 * Zend_Controller_Request_Apache404
 *
 * HTTP request object for use with Zend_Controller family. Extends basic HTTP
 * request object to allow for two edge cases when using Apache:
 * - Using Apache's 404 handler instead of mod_rewrite to direct requests
 * - Using the PT flag in rewrite rules
 *
 * In each case, the URL to check against is found in REDIRECT_URL, not
 * REQUEST_URI.
